April 26, 2006 marked 20th anniversary of the explosion at the nuclear power plant in the Ukrainian city of Chernobyl - the biggest technologic disaster in the history of humankind.
The plant is located 129 Km north of the Ukrainian capital of Kiev and has 4 reactors. The explosion occurred when numerous safety procedures were disregarded while testing the reactor number four.
At 1:23 am on April 26, 1986 a chain reaction in the reactor became uncontrollable, creating a series of explosions that killed more than 30 people immediately, while thousands died later from radiation sickness and other exposure-related diseases.
As a result of extreme radiation levels in the 30 Km radius around Chernobyl 135,000 people had to be evacuated.
